Abstract
An air mover which allows for both side-by-side and coaxial stacking. An air mover is essentially composed of substantially a cylindrical fan or motor housing with an air exhaust nozzle extending tangentially therefrom. The side-by-side stacking arrangement includes the interlocking of the stacking register of the handle of the air mover with the underside of the accessory flange at the distal end of the nozzle. The handle snugly nests within the space formed by the nozzle as it extends tangentially from the motor housing. The coaxial stacking involves the interlocking of a tab on the nozzle and a circular projection on one planar surface of the air mover with a slot and circular depression on the opposite planar of another air mover. The diameter of the circular depression being greater than the diameter of the circular projection and the slot being sized to receive the tab. Alone or in combination, the interlocking systems provide for compact storage and transportation.
